So I've never used fiberglass before but I have used epoxies. I mixed the resin with hardener as exactly as I could and mixed it and everything seemed fine. I put some on the plastic where I was going to put the fiberglass then put the cut cloth piece into the resin as the directions said.. as i pushed it in the epoxy turned into a gel and got really hot like it does when its hardening but the directions said I had 12 to 15 min and this was only after about 1 min. It then turned solid in about a minute after i pushed the fiber piece into it. What did I do wrong?? too much hardener??

The wired thing was that it was like pushing the fiber piece into the epoxy sped up the reaction.. I still have half the bottle left (about 4 oz) so hopefully I still have enough.. any ideas??

I just used barely enough gel that I thought I would need to coat the two pieces and I think I used 14 drops of hardener, mixed like a madman for 30sec, used the little stik that came with it to pour and spread onto a piece of wax paper with the cloth. After they were saturated, I think I had about 5-7min before it got gummy.
